Background: Buceng is a combination of plant of purwoceng (Pimpinella alpina Molk) and pasak bumi (Eurycomalongifolia Jack) that has been traditionally used to enhance adult male vitality. However, the mechanism of action of buceng has not been understood. This study was aimed to elucidate whether buceng could increasing Testosterone (Te), Luteinizing Hormone (LH), and Follicle Stimulating Horm...
Evolutionary mechanisms of habitat invasions, using the copepod Eurytemora affinis as a model system
The study of the copepod Eurytemora affinis has provided unprecedented insights into mechanisms of invasive success. In this invited review, I summarize a subset of work from my laboratory to highlight key insights gained from studying E. affinis as a model system. Invasive species with brackish origins are overrepresented in freshwater habitats. The copepod E. affinis is an example of such a b...
We compare the sequences for the mitochondrial cytochrome oxidase II gene of 13 species of the Drosophila obscura group. The survey includes six members of the D. affinis subgroup, four of the D. pseudoobscura subgroup, and three of the D. obscura subgroup. In all species, the gene is 688 nucleotides in length, encoding a protein of 229 amino acids plus the first position T of the stop codon. T...
Feeding ecology of white perch Morone americana larvae, a major component of the ichthyoplankton community in the estuarine turbidity maximum (ETM) region of upper Chesapeake Bay, was evaluated in years of contrasting physical conditions. In 1998, high river flow led to an ETM with high turbidity and pronounced salinity stratification. In 1999, under low river flow conditions, turbidities in th...
Trichomoniasis is one of the most common urinary-genital tract disease. The causal agent of trichomoniasis is flagellate protozoan called Trichomonas vaginalis. Metronidazole and tinidazole are the drug of choice for treatment. Carcinogenic and embryo-teratogenic effects of the mentioned drugs and resistance to metronidazole has been reported. According to cytotoxic effects of medicinal herbs i...
